Evinox UA10 Room Controller showing LP

I have an Evinox UA10 Room Controller showing an LP message and flickering constantly (like this). I have looked into the user manual but there's no mention of any LP. My first guess was that it stands for "Low Pressure" but the boiler shows a normal pressure. My second guess would be "Low Power". Tried to open it and it has a 3V Lithium Battery but it's glued to the motherboard so I'm not sure if it's normal to change its battery as removing it will damage the rest. I've been told it's plugged directly to the power so there is no need to change any battery.

Anybody had this problem before and has any advice?

How old is the controller? Might be that the 3v lithium battery has gone?
I would have expected longer than that. It appears to be a heat interface unit, looks like there’s technical assistance available, I’d try contacting them? Might be that they own the unit, or support it?

Hi, did you ever find out what the LP fault was? I’m having the same issue. No heating but hot water ok.
